The HP Microserver Gen10 currently does not boot unless ACPI is disabled. Since new ACPI testing images were made available I wanted to see if those fixed the issue. Sadly the issue is still present. When booting the debug image it hits the assert at: https://github.com/joyent/illumos-joyent/blob/b55712a7295a33023eab23147df4d72b5c128fe1/usr/src/uts/common/io/pciex/hotplug/pciehpc.c#L1260

Can you share what the value of the read register is at that point?

wiedi commented 5 years ago

It's 0x1028, so:

PCIE_SLOTCTL_PRESENCE_CHANGE_EN (0x8)
PCIE_SLOTCTL_HP_INTR_EN (0x20)
PCIE_SLOTCTL_DLL_STATE_EN (0x1000)

Doesn't the comment above ("check for power control bit to be OFF") contradict the assert? Maybe the logic is just switched?

Without the assert it goes to maintenance mode:

gen10_debug_noassert
